Patent JP-H10261401-A (JP)
Title: Battery
Inventor: YOSHIDA KENSUKE
IPC: H01M4/13
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To avoid the danger of breakdown and ignition when inner pressure rise of a battery is generated by a short-circuit between electrodes by disconnecting a breaking connection part, which is provided in a route for electrically connecting between divided electrodes, so as to generate the separated condition between divided electrode. SOLUTION: A protecting plate 28 is provided with notches 38a-38d from the periphery to a nearly central part thereof, and provided with a central part 37 by extruding. Breaking connection parts 36a-36d between sector parts 35a-35d and the central part 37 are formed into the thin structure having a narrow width, and the notches 38a-38d and the notches in the periphery of the breaking connection parts 36a-36d are filled with the adhesive agent for preventing the generation of short-circuit between the sector parts 35a-35d and the central part 37 and for the sealing structure of a battery container. When the inner pressure of a battery is raised by a short-circuit between the electrodes, a weak part of the breaking connection parts 36a-36d in the route for electrically connecting the divided electrodes is disconnected so as to avoid a danger of breakdown and ignition. Since the breaking connection parts 36a-36d are formed by working one aluminum plate so as to connect to the divided electrodes, generation of breakdown and ignition can be avoided without changing the conventional volume of a battery.

Abstract: PURPOSE:To realize energy economization, improve operation performance and simplify constitution of a state sensor by forming the state sensor of a condensor whose electrostatic capacity is varied depending upon the first conductor plate fixed on a hand operation part and the second conductor plate which moves in interlocking with the motion of the hand operation part. CONSTITUTION:As for a state sensor 15, a condenser 18 is formed of the first conductor plate 16 and the second conductor plate 17, and connected to an electric power supply VDD through a resistor 19, and also connected to the ground through an electric discharge resistor 20, and further connected with the input of a signal processing unit 21. If a hand operation part 26 is operated during the operation of a vacuum cleaner, the distance between the first and second conductor plates 16 and 17 is varied by the inertia of the second conductor plate 17 according to the movement of the hand operation part 26, and the electrostatic capacity of the condensor 18 varies. Accordingly, the voltage between both edges of the condenser 18 varies, and the voltage variation is detected by the signal processing unit 21, and the number of revolution of a motor 23 can be controlled through a phase control unit 22 according to the movement of the hand operation part 26. Further, when the hand operation part 26 is not operated, the electrostatic capacity of the condensor 18 is not varied, and the revolution of the motor 23 can be stopped.
